to me it sounds like he's saying "won't eat a bunch of things that make me smile"

and "used to color my whole day"

and "steal everything by myself"

aaaaand finally i think he just repeats fucked up when im living without you instead of changing to fucked up when im thinking about you. but maybe thats just me :P <3
